Description

Technical Field

[0001] This utility model relates to the field of door handles, and more particularly to a door handle with a dustproof structure for a lock hole. Background Technology

[0002] Chinese Patent No. CN221742306U discloses a handle with a support structure, including a base and a handle disposed on the upper end of the base. The base is provided with a keyhole for key insertion, and the keyhole is provided with an opening and closing component for opening and closing the keyhole. The component includes an opening and closing plate disposed on the keyhole that can be flipped on the keyhole. Blocking components are respectively provided on both sides of the keyhole to reduce the probability of the opening and closing plate automatically flipping. The blocking components include telescopic blocks disposed on both sides of the keyhole. The base is provided with a storage groove for storing the telescopic blocks when they retract. An elastic element is disposed between the bottom surface of the storage groove and the telescopic blocks to drive the telescopic blocks to partially extend out of the storage groove. The telescopic blocks are provided with an guiding component when the telescopic blocks automatically retract into the storage groove.

[0003] The opening and closing plate in the above structure can be flipped onto the keyhole to close it, thereby reducing the probability of dust and other objects entering the keyhole. The telescopic blocks at both ends of the storage slot can block the rotation of the telescopic blocks, reducing the probability of them automatically flipping without external force. However, when the opening and closing plate is open, it will overlap the surface of the telescopic block away from the keyhole. After the user opens the door lock with the key and pulls the key out of the keyhole, the opening and closing plate needs to be rotated again to close the keyhole. Utility Model Content

[0004] This utility model addresses the drawback of existing technologies where, after the key is removed from the keyhole, an additional rotating opening and closing plate is required to close the keyhole. It provides a door handle with a dustproof structure for the keyhole.

[0005] To solve the above-mentioned technical problems, the present invention provides a solution through the following technical method:

[0006] A door handle with a dustproof lock hole structure includes a handle body and a lock hole disposed on the handle body. The handle body is provided with a dustproof component for reducing dust from entering the lock hole. The dustproof component includes a protective cover disposed on the handle body to protect the lock hole. The protective cover is slidably disposed on the handle body via a guide sliding component. An automatic reset structure is provided on one side of the protective cover, which drives the protective cover to automatically and slowly return to cover the lock hole after sliding away from the lock hole. The automatic reset structure includes a reset spring disposed on one side of the protective cover for driving the protective cover to reset and a damping component disposed in the sliding direction of the protective cover and away from the reset spring for slowing down the reset speed of the protective cover.

[0007] With the above solution, the reset spring can pull the protective cover towards the keyhole when it is far away from the keyhole, and the damping component can reduce the speed of the protective cover during reset, thus giving the operator enough time to turn the key to open the door lock. Since the reset spring can gradually pull the protective cover to reset and automatically cover the keyhole surface, no additional operation is required, making the use of the protective cover more convenient.

[0008] Preferably, the guide sliding component includes two guide plates that are parallel and spaced apart on the handle body along the sliding direction of the protective cover, and each pair of guide plates has a sliding groove on one side for the protective cover to be partially inserted and slide therein.

[0009] Using the above solution, two guide plates are arranged in parallel on the handle body, and sliding grooves are respectively provided on the opposite side of the two guide plates, so that the protective cover can be partially inserted into the two sliding grooves and guided to slide in the two sliding grooves.

[0010] Preferably, the reset spring is disposed in the sliding groove, and both ends of the reset spring are respectively connected to the side wall of the sliding groove and the side wall of the protective cover.

[0011] Preferably, the damping component includes a damping strip disposed at the bottom of each of the two sliding grooves, with one end away from the sliding groove abutting against the protective cover and providing damping for the sliding of the protective cover. The damping strip is disposed at the bottom of the sliding groove via a detachable component.

[0012] Using the above solution, the damping strip can be installed to the bottom of the sliding groove through a detachable structure. When the damping strip is installed to the bottom of the sliding groove, its surface can abut against the surface of the protective cover, thereby providing damping for the movement of the protective cover, reducing the speed at which the protective cover resets under the pull of the reset spring, and giving the operator enough time to unlock the door lock.

[0013] Preferably, the detachable component includes magnets that can attract each other, respectively provided on the inner wall of the sliding groove end and the side wall of the damping strip. The end of the sliding groove away from the magnet is provided with a slot for the damping strip to pass through and be inserted into the sliding groove. The magnetic force between the two magnets is greater than the frictional force between the damping strip and the protective cover.

[0014] Using the above scheme, the magnets set at the end of the sliding groove and on the side wall of the damping strip can attract each other when the damping strip is inserted from the slot into the sliding groove, thereby reducing the probability of the damping strip coming out of the sliding groove. The slots facilitate the installation or removal of the damping strip from the sliding groove. By setting the attraction between the two magnets to be greater than the friction between the damping strip and the protective cover, the probability of the damping strip moving when the protective cover is reset by the pull of the reset spring can be reduced.

[0015] Preferably, the end of the damping bar away from the magnet extends out of the slot, and a pull ring is provided at the point where the damping bar extends out of the slot to facilitate the operator to pull the damping bar out of the sliding groove.

[0016] Using the above solution, the pull ring located where the damping strip extends out of the slot allows the operator to easily pull the damping strip out of the sliding groove. At the same time, the damping strip is detachably installed in the sliding groove, so that when the damping strip wears out after a long period of use, it can be removed from the sliding groove for replacement.

[0017] Preferably, a position limiting component is provided between the two guide plates to ensure that the protective cover covers the surface of the keyhole when reset.

[0018] Preferably, the position limiting component includes a limiting baffle disposed between the two guide plates, with both ends respectively connected to the bottom of the two sliding grooves, and the limiting baffle is provided with a through hole for the reset tension spring to pass through.

[0019] Using the above solution, the limiting baffle set between the two guide plates can block the reset movement of the protective cover when it is reset to cover the surface of the keyhole, thereby keeping the protective cover in the state of covering the surface of the keyhole.

[0020] This utility model has significant technical effects due to the adoption of the above technical solutions: the reset spring can pull the protective cover towards the key hole when it is far away from the key hole, and the damping component can reduce the speed of the protective cover during reset, thus giving the operator enough time to turn the key to open the door lock. Because the reset spring can gradually pull the protective cover to reset and automatically cover the surface of the key hole, no additional operation is required, making the use of the protective cover more convenient.

[0033] Example

[0034] A door handle with a dustproof lock hole structure, reference Figures 1-2 , Figures 5-6 The device includes a handle body 1 and a lock hole 2 disposed on the handle body 1. The handle body 1 is provided with a dustproof component to reduce the entry of dust and other objects into the lock hole 2. The dustproof component includes a protective cover 3 disposed on the handle body 1 to protect the lock hole 2. The protective cover 3 is slidably disposed on the handle body 1 by a guide sliding component. An automatic reset structure is provided on one side of the protective cover 3, which drives the protective cover 3 to automatically and slowly reset and cover the lock hole 2 after the protective cover 3 slides away from the lock hole 2. The automatic reset structure includes a reset spring 4 disposed on one side of the protective cover 3 to drive the protective cover 3 to reset and a damping component disposed in the sliding direction of the protective cover 3 and away from the reset spring 4 to slow down the reset speed of the protective cover 3.

[0035] The guide sliding component includes two guide plates 5 arranged parallel to each other on the handle body 1 along the sliding direction of the protective cover 3. Each pair of guide plates 5 has a sliding groove 6 on one side for the protective cover 3 to be partially inserted and slide therein. The reset spring 4 is arranged in the sliding groove 6, and the two ends of the reset spring 4 are respectively connected to the side wall of the sliding groove 6 and the side wall of the protective cover 3.

[0036] refer to Figures 5-10The damping component includes a damping strip 7, which is disposed at the bottom of the two sliding grooves 6, with its end away from the sliding groove 6 abutting against the protective cover 3 and providing damping for the sliding of the protective cover 3. The damping strip 7 is disposed at the bottom of the sliding groove 6 through a detachable component. The detachable component includes magnets 8 that can attract each other, disposed on the inner wall of the end of the sliding groove 6 and the side wall of the damping strip 7, respectively. The end of the sliding groove 6 away from the magnet 8 is provided with a slot 9 for the damping strip 7 to pass through and insert into the sliding groove 6. In this embodiment, the width of the slot 9 is greater than the width of the sliding groove 6, so that the inner wall of the slot 9 can support the damping strip 7 and reduce the probability of it coming out of the sliding groove 6. The magnetic force between the two magnets 8 is greater than the frictional force between the damping strip 7 and the protective cover 3. The end of the damping strip 7 away from the magnet 8 extends out of the slot 9, and a pull ring 10 is provided at the point where the damping strip 7 extends out of the slot 9 to facilitate the operator to pull the damping strip 7 out of the sliding groove 6.

[0037] refer to Figures 5-6 A position limiting component is provided between the two guide plates 5 to ensure that the protective cover 3 covers the surface of the lock hole 2 when it is reset. The position limiting component includes a limiting baffle 11 between the two guide plates 5, the two ends of which are respectively connected to the bottom of the two sliding grooves 6. The limiting baffle 11 is provided with a through hole 12 for the reset tension spring 4 to pass through.

[0038] Specific process: When the key needs to be inserted into the lock hole 2, firstly, slide the protective cover 3 away from the limiting baffle 11. The reset spring 4 set in the slot 9 will be stretched due to the movement of the protective cover 3. When the protective cover 3 is completely disengaged from the lock hole 2, the key can be inserted into the lock hole 2 to unlock the door. During the process of unlocking the door lock through the keyhole, the reset spring 4 will pull the protective cover 3 to gradually return to its original position. The damping strip 7 set in the slot 9 will rub against the side wall of the protective cover 3, thereby slowing down the speed of the protective cover 3 during the return process, giving the operator enough time to unlock the door lock. When the protective cover 3 is pulled by the reset spring 4 and comes into contact with the limiting baffle 11, the limiting baffle 11 will restrict the movement of the protective cover 3. At this time, the protective cover 3 is in a state of covering the surface of the lock hole 2, sealing the lock hole 2, reducing the probability of dust and other objects entering the lock hole 2, and improving the service life of the door lock.
